!!!!!!HELPPP!!!!!!

Hey there! I'm happy to help!

A permutation is focused on a specific order, while a combination is not focused on the order but on the content of what is grouped.

AB and BA are different permutations because they are in different orders, but they are the same combination because they both contain the letters A and B.

So, we see that AB and BA are one combination.

AC and CA are also another combination because they are made up of the letters A and C.

Same goes for BC and CB, this is also one combinations.

This totals up to C. 3 combinations. Now you know the difference between permutations and combinations!

Have a wonderful day!

A truck with 36-in.-diameter wheels is traveling at 55 mi/h.
kkurt [141]

Answer:

The angular speed is 3,227 rad/min

Step-by-step explanation:

Remember that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

The circumference is equal to

C=\pi D

we have

D=36\ in

substitute

C=\pi (36)

C=36\pi\ in

step 2

we know that

The speed of the wheel is 55 mi/h

<em><u>Convert to mi/min</u></em>

55 mi/h=55/60 mi/min

<u><em>Convert to in/min</em></u>

(55/60) mi/min=55*63,360/60 in/min= 58,080 in/min

we know that

The circumference of the wheel subtends a central angle of 2π radians

so

using proportion

Find out how much radians are 58,080 inches

\frac{36\pi }{2\pi }=\frac{58,080}{x} \\\\x=2*58,080/36\\\\x=3,226.67 \ rad

therefore

The angular speed is 3,227 rad/min
